Which Battery Should I Choose?
Please check your manual before purchasing a replacement battery for your power tool. Different chemistries, voltages, and capacity can be overwhelming. Sometimes, a 14.4 Volt battery for Dewalt DW984K may also be listed under DW984K 2.0Ah or DW984K NiMH. All three batteries fit the same tool, but why choose one or the other?

Ni-CD batteries last the shortest amount of time and need to be recharged often (but you get more charge cycles). Ni-MH batteries may cost more, however have no memory effect, they last longer due to a higher capacity, hold a longer charge, and they contain no toxic chemicals that are harmful. However, you won't get as many cycles for some Ni-MH batteries. Li-Ion has a very high energy/mass, meaning it is a light weight battery that will store a lot of energy with no memory effect. In general, the higher the capacity (mAh), the longer the battery will last. Installing batteries with a different capacity will not affect the operation of a device as long as the voltage matches.
